Plex is a free font developed IBM Brand & Experience team (BX&D) for use as a corporate typeface for IBM. The font was released open-source and anybody can use it.

The family includes a Sans, Sans Condensed, Mono, and Serif and has excellent legibility in print, web and mobile interfaces.

Plex’s three designs work well independently, and even better together. Use the Sans as a contemporary compadre, the Serif for editorial storytelling, or the Mono to show code snippets. The unexpectedly expressive nature of the italics give you even more options for your designs.
